Reviewed October 16, 2026. Examples are fictional and illustrate record review, not individual tax or legal advice.
Year-to-date gross earnings and W-2 Box 1 are not interchangeable labels. A paystub’s gross total may include compensation that is treated differently when federal taxable wages are reported.
Compare the same employer and year
Use the final relevant payroll statement and the W-2 from that employer for that calendar year. A statement issued before the final payroll run may be incomplete. Corrected payroll, off-cycle payments, or a W-2c can also change the comparison. Ask payroll which version is current.
Understand pre-tax retirement deferrals
IRS guidance explains that qualifying pre-tax salary-reduction contributions are excluded from Box 1, while they generally remain subject to Social Security and Medicare taxes. Designated Roth contributions are different. Do not subtract every deduction from gross pay: after-tax deductions do not become pre-tax simply because they appear on the stub.
Work through a limited example
Assume fictional annual gross earnings of $50,000 and $3,000 in qualifying traditional 401(k) salary deferrals, with no other differences. Box 1 would be $47,000 in this simplified example. It is not a universal formula: benefits, taxable noncash compensation, corrections, and other items can change the result.
Match the label before comparing the total
| Record or field | What to compare |
|---|---|
| Pay stub YTD gross | Employer’s cumulative gross-earnings definition; it is not automatically federal taxable wages. |
| W-2 Box 1 | Annual wages, tips and other compensation reportable for federal income tax. |
| W-2 Box 2 | Federal income tax withheld during the year; compare it with the payroll withholding total, not gross pay. |
| W-2 Boxes 3 and 5 | Social Security and Medicare wage bases; they can differ from Box 1 and from each other. |
| Pay stub YTD net | Cumulative take-home pay after employee deductions; it is not a substitute for Box 1. |
In the $50,000 example above, a separate $1,000 designated Roth 401(k) contribution would not reduce the $47,000 Box 1 amount further. Federal tax withholding also does not reduce it. Under the stated assumptions and ordinary covered wages, Boxes 3 and 5 would remain $50,000 because the traditional deferral remains subject to FICA.
A practical year-end reconciliation checklist
- Match the employee, employer and calendar year. Include final and off-cycle payroll records, and confirm whether corrected versions exist.
- Identify how the payroll system defines YTD gross and federal taxable wages. Use the federal taxable-wage field as a comparison point when available.
- List each difference once: qualifying exclusions, taxable items not included in the gross figure being compared, or documented corrections. Ask payroll to explain unfamiliar codes.
- Reconcile federal income tax withheld separately to Box 2. Do not subtract it from wages to force a Box 1 match.
- Keep the payroll explanation and supporting records. If a reporting error remains, request the employer’s correction process.
A useful request to payroll is: “Please reconcile my final YTD gross earnings to W-2 Box 1 for this employer and year, showing each adjustment and whether my statement or W-2 has been corrected.” Avoid sending sensitive identifiers through an unsecured channel.
Can Box 1 be higher than the gross figure on a pay stub?
It can happen when the gross field you are comparing omits taxable compensation reported on the W-2, or when the statement is incomplete. Confirm the source records rather than assuming every difference is a pre-tax deduction. The result depends on what that particular payroll system includes.
For earlier steps, see what YTD means and the payroll reconciliation checklist. To model regular federal income-tax withholding on one check, use the federal withholding calculator. It does not reconstruct your annual Box 1 or determine whether a W-2 is correct. If the underlying statement is wrong, follow the pay stub correction guide.
Request the taxable-wage bridge
Ask payroll for a reconciliation from annual gross earnings to federal taxable wages. Each difference should have a named category and supporting amount. Compare the federal income tax withholding total separately from wages; tax withheld is not a reduction of Box 1 wages.
Use the correct document for the purpose
An income requester may ask for recent paystubs, a W-2, or both. Follow their document instructions without changing legitimate amounts to force a match. If an error exists, request a correction from the employer rather than editing a tax form yourself.
Keep your evidence together
Store the year-end statement, employer explanation, W-2, and any corrected documents together. The goal is an explainable difference, not identical totals in every box.
